Gypsum-containing products must have a particle size less than 1/8 inch. Fluid application is acceptable. Do not exceed annual application rates of 5 tons/acre for the purposes defined in this standard. Use a soil analysis no older than 1 year that provides cation exchange capacity (CEC), calcium, magnesium, pH,

Using gypsum- (calcium sulfate dihydrate) derived products to change the physical and/or chemical properties of soil. Improve soil health by improving physical/chemical properties and increasing infiltration of the soil. Improve surface water quality by reducing dissolved phosphorus concentrations in surface runoff and subsurface drainage.

For soybean and other crops, gypsum can be applied at rates of up to 1,000-4,000 pounds per acre (lbs/acre) to enhance yield and quality. Peanuts: For peanuts, apply gypsum at 0.5 tons per acre to increase yield and calcium concentration in peanut seeds.

For soil amendment, apply GYPSOIL at a rate of one to two tons per acre every one to two years. For sulfur only, typical rates are 300 to 500 lbs./ A but growers often opt for the higher rates to achieve both benefits. For peanut production, rates depend on the variety of peanut grown and wheterh you are producing seed peanuts.

Oct 26, 2012 · Has anyone applied 1 ton or more gypsum per acre for a year or two in a row? Did you see any change in soil test levels (Ca ppm or base saturation) after the gypsum application? Do you think the gypsum actually noticeably changed the physical properties of your soil (less crusting / ponding, works easier, etc)? I can't decide.

Aug 9, 2022 · • Gypsum has been shown to improve surface infiltration rates by inhibiting or delaying surface seal formation. • Gypsum application to soil can reduce soil erosion by flocculating clay particles so that they settle out of surface water and thus are less prone to be moved offsite. • The calcium in gypsum can bind with phosphorus to

Sep 29, 2014 · Applying gypsum as a source of calcium and sulfur and to improve soil structure is a good practice. Determining the appropriate rate depends on economics and product type. By-products are usually applied at 0.5 to 1 ton per acre every 3 or 4 years while pelletized ag gypsum is applied at 200 to 400 pounds per acre every 1 to 2 years.

Nov 15, 2013 · Gypsum (CaSO4 • 2H2O) contains 17-20% calcium and 13-16% sulfur. This equates to roughly 400 pounds of calcium and 320 pounds of sulfate-sulfur for a typical application rate of 1 ton per acre, according to Ron Chamberlain, chief agronomist for GYPSOIL/BRM, a Chicago-based company that markets GYPSOIL brand gypsum.

Mar 27, 2022 · Applying Gypsum to Large Fields. For broadcast application on large fields, apply at rates between 50 and 400 pounds per acre, or 2-10 pounds per 1000 square feet. Gypsum is best applied as a field dress shortly before planting, so calcium is present and available at all levels of the soil column.

Oct 23, 2019 · A standard recommendation is 10-20 pounds of gypsum per 100 square feet of soil. Two or three handfuls per square meter should be enough if you use powdered gypsum. You should work the gypsum to a depth of 6-12 inches into the soil. How Long Does Gypsum Take To Work. Gypsum typically takes several months to show results in improving soil structure.
